Hi,
I have a List<data> which i am trying to loop and pass it to some function.
C#
IEnumerable<EntityObject> Data  = entity.get();
LstAll = new Employee(); 
foreach (EntityObject o in Data)
{
  Employee e = new Employee();
  DeleteData(0,e);
  LstAll.Add(e);
}

now i want to use lamba expression so that i can remove the Foreach loop and call the DeleteData.
C#
LstAll.Add(from o in Data  
           let c = DeleteData(o,Employee e));

This code is giving me error.
Any suggestion Plz help.

[Edit: Code block added]

What is the error?

its syntactically wrong.

The solution here:
Linq Query - Call Method.[^]

might solve your issue.

You have 2 operations to perform, fill list and delete record, both cannot be done.

Each Linq expression must have a select.
C#
from ... in ... select ...;

Your example data is incomplete or maybe wrong. You talk about List<data> but this is nowhere visible in your code.
Your LstAll seems to be a list (you call Add(...) in the loop), but initialization is by a single element (new Employee() is not likely to be a list, right?).

Please revise your question and carefully check the code in the question so it exactly matches what you have in your homework assignment.

Cheers

PS: What does DeleteData(...) doing? If it removes some item from the list it loops over, the program is broken.
PPS: If the problem is to add a range of elements to a list, then use the AddRange(...) method.
PPPS: Is this a typo or don't you understand where to use/don't use type names (see Employee):
C#
LstAll.AddRange(from o in Data let c = DeleteData(o,Employee e) ... select ...);
or is it rather the following?
C#
LstAll.AddRange(from o in Data let c = DeleteData(o, new Employee()) ... select ...);
